An end of an adjustable bell section expansion cone assembly 28 is coupled to another end of the extension actuator assembly 26. In an exemplary embodiment, the adjustable bell section expansion cone assembly 28 may be, or may include elements, of one or more conventional adjustable expansion devices for radially expanding and plastically deforming wellbore casing, or equivalents thereof.

An end of an adjustable casing expansion cone assembly 30 is coupled to another end of the adjustable bell section expansion cone assembly 28. In an exemplary embodiment, the adjustable casing expansion cone assembly 30 may be, or may include elements, of one or more conventional adjustable expansion devices for radially expanding and plastically deforming wellbore casing, or equivalents thereof.

An end of a packer setting tool assembly 32 is coupled to another end of the adjustable casing expansion cone assembly 30. In an exemplary embodiment, the packer setting tool assembly 32 may be, or may include elements, of one or more conventional adjustable expansion devices for controlling the operation of a conventional packer, or equivalents thereof.

An end of a packer assembly 36 is coupled to another end of the stinger assembly 34. In an exemplary embodiment, the packer assembly 36 may be, or may include elements, of one or more conventional packers.

As illustrated in FIG. 1, in an exemplary embodiment, during operation of the system 10, an expandable wellbore casing 100 is coupled to and supported by the casing lock assembly 24 of the system. The system 10 is then positioned within a wellbore 102 that traverses a subterranean formation 104 and includes a preexisting wellbore casing 106.

As illustrated in FIG. 2, in an exemplary embodiment, the extension actuator assembly 26 is then operated to move the adjustable bell section expansion cone assembly 28, adjustable casing expansion cone assembly 30, packer setting tool assembly 32, stinger assembly 34, packer assembly 36 downwardly in a direction 108 and out of an end of the expandable wellbore casing 100. After the adjustable bell section expansion cone assembly 28 and adjustable casing expansion cone assembly 30 have been moved to a position out of the end of the expandable wellbore casing 100, the adjustable bell section expansion cone assembly and adjustable casing expansion cone assembly are then operated to increase the outside diameters of the expansion cone assemblies. In an exemplary embodiment, the increased outside diameter of the adjustable bell section expansion cone assembly 28 is greater than the increased outside diameter of the adjustable casing expansion cone assembly 30.

As illustrated in FIG. 3, in an exemplary embodiment, the ball gripper assembly 16 is then operated to engage and hold the position of the expandable tubular member 100 stationary relative to the tubular support member 12. The tension actuator assembly 18 is then operated to move the adjustable bell section expansion cone assembly 28, adjustable casing expansion cone assembly 30, packer setting tool assembly 32, stinger assembly 34, packer assembly 36 upwardly in a direction 110 into and through the end of the expandable wellbore casing 100. As a result, the end of the expandable wellbore casing 100 is radially expanded and plastically deformed by the adjustable bell section expansion cone assembly 28 to form a bell section 112. In an exemplary embodiment, during the operation of the system 10 described above with reference to FIG. 3, the casing lock assembly 24 may or may not be coupled to the expandable wellbore casing 100.

In an exemplary embodiment, the length of the end of the expandable wellbore casing 100 that is radially expanded and plastically deformed by the adjustable bell section expansion cone assembly 28 is limited by the stroke length of the tension actuator assembly 18. In an exemplary embodiment, once the tension actuator assembly 18 completes a stroke, the ball gripper assembly 16 is operated to release the expandable tubular member 100, and the tubular support 12 is moved upwardly to permit the tension actuator assembly to be re-set. In this manner, the length of the bell section 112 can be further extended by continuing to stroke and then re-set the position of the tension actuator assembly 18. Note, that, during the upward movement of the tubular support 12 to re-set the position of the tension actuator assembly 18, the expandable tubular wellbore casing 100 is supported by the expansion surfaces of the adjustable bell section expansion cone assembly 28.

As illustrated in FIG. 4, in an exemplary embodiment, the casing lock assembly 24 is then operated to engage and maintain the position of the expandable wellbore casing 100 stationary relative to the tubular support 12. The adjustable bell section expansion cone assembly 28, adjustable casing expansion cone assembly 30, packer setting tool assembly 32, stinger assembly 34, and packer assembly 36 are displaced downwardly into the bell section 112 in a direction 114 relative to the expandable wellbore casing 100 by operating the extension actuator 26 and/or by displacing the system 10 downwardly in the direction 114 relative to the expandable wellbore casing. After the adjustable bell section expansion cone assembly 28 and adjustable casing expansion cone assembly 30 have been moved downwardly in the direction 114 into the bell section 112 of the expandable wellbore casing 100, the adjustable bell section expansion cone assembly is then operated to decrease the outside diameter of the adjustable bell section expansion cone assembly. In an exemplary embodiment, the decreased outside diameter of the adjustable bell section expansion cone assembly 28 is less than the increased outside diameter of the adjustable casing expansion cone assembly 30. In an exemplary embodiment, during the operation of the system illustrated and described above with reference to FIG. 4, the ball gripper 16 may or may not be operated to engage the expandable wellbore casing 100.

As illustrated in FIG. 5, in an exemplary embodiment, the casing lock assembly 24 is then disengaged from the expandable wellbore casing 100 and fluidic material 116 is then injected into the system 10 through the tubular support 12 to thereby pressurize an annulus 118 defined within the expandable wellbore casing below the cup sub assembly 22. As a result, a pressure differential is created across the cup seal assembly 22 that causes the cup seal assembly to apply a tensile force in the direction 120 to the system 10. As a result, the system 10 is displaced upwardly in the direction 120 relative to the expandable wellbore casing 100 thereby pulling the adjustable casing expansion cone assembly 30 upwardly in the direction 120 through the expandable wellbore casing thereby radially expanding and plastically deforming the expandable wellbore casing.

In an exemplary embodiment, the tension actuator assembly 16 may also be operated during the injection of the fluidic material 116 to displace the adjustable casing expansion cone assembly 30 upwardly relative to the tubular support 12. As a result, additional expansion forces may be applied to the expandable wellbore casing 100.

As illustrated in FIG. 6, in an exemplary embodiment, the radial expansion and plastic deformation of the expandable wellbore casing using the adjustable casing expansion cone assembly 30 continues until the packer assembly 36 is positioned within a portion of the expandable tubular member above the bell section 112. The packer assembly 36 may then be operated to engage the interior surface of the expandable wellbore casing 100 above the bell section 112.

In an exemplary embodiment, after the packer assembly 36 is operated to engage the interior surface of the expandable wellbore casing 100 above the bell section 112, a hardenable fluidic sealing material 122 may then be injected into the system 10 through the tubular support 12 and then out of the system through the packer assembly to thereby permit the annulus between the expandable wellbore casing and the wellbore 102 to be filled with the hardenable fluidic sealing material. The hardenable fluidic sealing material 122 may then be allowed to cure to form a fluid tight annulus between the expandable wellbore casing 100 and the wellbore 102, before, during, or after the completion of the radial expansion and plastic deformation of the expandable wellbore casing.

As illustrated in FIG. 7, in an exemplary embodiment, the fluidic material 116 is then re-injected into the system 10 through the tubular support 12 to thereby re-pressurize the annulus 118 defined within the expandable wellbore casing below the cup sub assembly 22. As a result, a pressure differential is once again created across the cup seal assembly 22 that causes the cup seal assembly to once again apply a tensile force in the direction 120 to the system 10. As a result, the system 10 is displaced upwardly in the direction 120 relative to the expandable wellbore casing 100 thereby pulling the adjustable casing expansion cone assembly 30 upwardly in the direction 120 through the expandable wellbore casing thereby radially expanding and plastically deforming the expandable wellbore casing and disengaging the stinger assembly 34 from the packer assembly 36. In an exemplary embodiment, during this operational mode, the packer assembly 36 prevents the flow of fluidic materials out of the expandable wellbore casing 100. As a result, the pressurization of the annulus 118 is rapid and efficient thereby enhancing the operational efficiency of the subsequent radial expansion and plastic deformation of the expandable wellbore casing 100.

In an exemplary embodiment, the tension actuator assembly 16 may also be operated during the re-injection of the fluidic material 116 to displace the adjustable casing expansion cone assembly 30 upwardly relative to the tubular support 12. As a result, additional expansion forces may be applied to the expandable wellbore casing 100.

As illustrated in FIG. 8, in an exemplary embodiment, the radial expansion and plastic deformation of the expandable wellbore casing using the adjustable casing expansion cone assembly 30 continues until the adjustable casing expansion cone assembly 30 reaches the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106. At which point, the system 10 may radially expand the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 and the surrounding portion of the preexisting wellbore casing. Consequently, in an exemplary embodiment, during the radial expansion of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106, the tension actuator assembly 16 is also operated to displace the adjustable casing expansion cone assembly 30 upwardly relative to the tubular support 12. As a result, additional expansion forces may be applied to the expandable wellbore casing 100 and the preexisting wellbore casing 106 during the radial expansion of the portion 124 of the expandable wellbore casing that overlaps with the preexisting wellbore casing.

As illustrated in FIG. 9, in an exemplary embodiment, the entire length of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 is not radially expanded and plastically deformed. Rather, only part of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 is radially expanded and plastically deformed. The remaining part of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 is then cut away by operating the casing cutter assembly 14.

As illustrated in FIG. 10, the remaining part of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 that is cut away by operating the casing cutter assembly 14 is then also carried out of the wellbore 102 using the casing cutter assembly.

Furthermore, in an exemplary embodiment, the inside diameter of the expandable wellbore casing 100 above the bell section 112 is equal to the inside diameter of the portion of the preexisting wellbore casing 106 that does not overlap with the expandable wellbore casing 100. As a result, a wellbore casing is constructed that includes overlapping wellbore casings that together define an internal passage having a constant cross-sectional area.

A release piston 14084 mounted upon the tubular lower mandrel 14006 defines a radial passage 14084 a for mounting a burst disk 14086 includes sealing elements, 14084 b, 14084 c, and 14084 d. The sealing elements, 14084 b and 14084 d, sealing the interface between the release piston 14084 and the tubular lower mandrel 14006. An end face of the release piston 14084 is positioned in opposing relation to an end face of the locking dogs 14080.

A release sleeve 14088 that receives and is mounted upon the locking dogs 14080 and the release piston 14084 includes an internal flange 14088 a at one end that sealingly engages the tubular lower mandrel 14006. A bypass sleeve 14090 that receives and is mounted upon the release sleeve 14088 includes an internal flange 14090 a at one end.

In an exemplary embodiment, during operation of the casing cutter assembly 14, the retracting spring 14044 is compressed and thereby applies a biasing spring force in a direction 14092 from the lower tubular mandrel 14006 to the tubular spring housing 14034 that, in the absence of other forces, moves and/or maintains the upper cam assembly 14052 and the upper casing cutter segments 14054 out of engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060. In an exemplary embodiment, during operation of the casing cutter assembly 14, an external threaded connection 12 a of an end of the tubular support member 12 is coupled to the internal threaded connection 14002 d of the upper tubular tool joint 14002 and an internal threaded connection 16 a of an end of the ball gripper assembly 16 is coupled to the external threaded connection 14068 f of the tubular member 14068.

The upper cam assembly 14052 and the upper casing cutter segments 14054 may be brought into engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060 by pressurizing an annulus 14094 defined between the lower tubular mandrel 14006 and the tubular spring housing 14034. In particular, injection of fluidic materials into the cam cutter assembly 14 through the longitudinal passage 14006 b of the lower tubular mandrel 14006 and into the radial passage 14006 ba may pressurize the annulus 14094 thereby creating sufficient operating pressure to generate a force in a direction 14096 sufficient to overcome the biasing force of the retracting spring 14044. As a result, the spring housing 14034 may be displaced in the direction 14096 relative to the lower tubular mandrel 14006 thereby displacing the tubular upper hinge sleeve 14050, upper cam assembly 14052, and upper casing cutter segments 14054 in the direction 14096.

In an exemplary embodiment, as illustrated in FIGS. 11P, 11Q and 11R, the displacement of the upper cam assembly 14052 and upper casing cutter segments 14054 in the direction 14096 will cause the lower casing cutter segments 14058 to ride up the cam surfaces of the cam arms of the upper cam assembly 14052 while also pivoting about the lower tubular hinge segment 14064, and will also cause the upper casing cutter segments 14054 to ride up the cam surfaces of the cam arms of the lower cam assembly 14060 while also pivoting about the upper tubular hinge segment 14050.

In an exemplary embodiment, during the operation of the casing cutter assembly 14, when the upper and lower casing cutter segments, 14054 and 14058, brought into axial alignment in a radially expanded position, the casing cutter elements of the casing cutter segments are brought into intimate contact with the interior surface of a pre-selected portion of the expandable wellbore casing 100. The casing cutter assembly 14 may then be rotated to thereby cause the casing cutter elements to cut through the expandable wellbore casing. The portion of the expandable wellbore casing 100 cut away from the remaining portion on the expandable wellbore casing may then be carried out of the wellbore 102 with the cut away portion of the expandable wellbore casing supported by the casing cutter elements.

In an exemplary embodiment, the upper cam assembly 14052 and the upper casing cutter segments 14054 may be moved out of engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060 by reducing the operating pressure within the annulus 14094.

In an alternative embodiment, as illustrated in FIGS. 11S, 11T, 11U and 11V, during operation of the casing cutter assembly 14, the upper cam assembly 14052 and the upper casing cutter segments 14054 may also be moved out of engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060 by sensing the operating pressure within the longitudinal passage 14006 b of the lower tubular mandrel 14006. In particular, as illustrated in FIG. 11T, if the operating pressure within the longitudinal passage 14006 b and radial passage 14006 bb of the lower tubular mandrel 14006 exceeds a predetermined value, the burst disc 14086 will open the passage 14084 a thereby pressurizing the interior of the tubular release sleeve 14088 thereby displacing the tubular release sleeve 14088 downwardly in a direction 14092 away from engagement with the locking dogs 14080.

As a result, as illustrated in FIG. 11U, the locking dogs 14080 are displaced outwardly in the radial directed and thereby released from engagement with the lower tubular mandrel 14006 thereby permitting the lower casing cutter segments 14058 and the lower cam assembly 14060 to be displaced downwardly relative to the lower tubular mandrel.

As a result, as illustrated in FIG. 11V, the operating pressure within the lower tubular mandrel 14066 may then cause the lower tubular mandrel to be displaced downwardly in the direction 14094 relative to the tubular lower mandrel 14006 and the retracting piston 14074. As a result, the lower tubular mandrel 14066, the lower casing cutter segments 14058, the lower cam assembly 14060, and tubular lower hinge sleeve 14064 are displaced downwardly in the direction 14094 relative to the tubular spring housing 14034 thereby moving the lower casing cutter segments 14058 and the lower cam assembly 14060 out of engagement with the upper cam assembly 14052 and the upper casing cutter segments 14054.

In an exemplary embodiment, as illustrated in FIGS. 11W, 11X, and 11Y, during operation of the casing cutter assembly 14, the casing cutter assembly 14 senses the diameter of the expandable wellbore casing 100 using the upper toggle links, 14022 and 14028, lower toggle links, 14024 and 14030, and triggers, 14026 and 14032, and then prevents the engagement of the upper cam assembly 14052 and the upper casing cutter segments 14054 with the lower casing cutter segments 14058 and the lower cam assembly 14060.

In particular, as illustrated in FIG. 11W, anytime the upper toggle links, 14022 and 14028, and lower toggle links, 14024 and 14030, are positioned within a portion of the expandable wellbore casing 100 that has been radially expanded and plastically deformed by the system 10, the triggers, 14026 and 14032, will be pivoted by the engagement arms, 14024 d and 14030 d, of the lower toggle links, 14024 and 14030, to a position in which the triggers will no longer engage the internal flange 14034 d of the end of the tubular spring housing 14034 thereby permitting the displacement of the tubular spring housing in the direction 14096. As a result, the upper cam assembly 14052 and the upper casing cutter segments 14054 can be brought into engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060. In an exemplary embodiment, the upper toggle links, 14022 and 14028, and the lower toggle links, 14024 and 14030, are spring biased towards the position illustrated in FIG. 11W.

Conversely, as illustrated in FIG. 11X, anytime the upper toggle links, 14022 and 14028, and lower toggle links, 14024 and 14030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10, the triggers, 14026 and 14032, will be maintained in a position in which the triggers will engage the internal flange 14034 d of the end of the tubular spring housing 14034 thereby preventing the displacement of the tubular spring housing in the direction 14096. As a result, the upper cam assembly 14052 and the upper casing cutter segments 14054 cannot be brought into engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060. In an exemplary embodiment, the triggers, 14026 and 14032, are spring biased towards the position illustrated in FIG. 11X.

In an exemplary embodiment, as illustrated in FIG. 11Y, the tubular spring housing 14034 may be displaced upwardly in the direction 14098 even if the upper toggle links, 14022 and 14028, and lower toggle links, 14024 and 14030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10.

In an exemplary embodiment, as illustrated in FIGS. 11Z1 to 11Z4, 11AA1 to 11AA4, 11AB1 to 11AB4, 11AC1 to 11AC4, 11AD, and 11AE, the tubular spring housing 14034 of the casing cutter assembly 14 defines internal annular recesses 14034 k and 14034 l, spaced apart by an internal flange 14034 m, the tubular toggle bushing 14008 defines an external annular recess 14008 ac, and the casing cutter assembly further includes pins, 14100 a and 14100 b and 14102 a and 14102 b, mounted in holes 14008 j and 14008 o and 14008 k and 14008 n, respectively, of the tubular toggle bushing, and a one-shot deactivation device 14104 mounted on the tubular toggle bushing between the pins, 14100 a and 14100 b and 14102 a and 14102 b.

The one-shot deactivation device 14104 includes a tubular body 14104 a that defines radial holes, 14104 b and 14014 c, and includes an external annular recess 14104 d at one end, a centrally positioned external flange 14104 e, a centrally positioned internal annular recess 14104 f, and an external annular recess 14104 g at another end. An engagement member 14106 that includes a base member 14106 a having a tapered end 14106 b and a key member 14106 c having a tapered end 14106 d is received within a portion of the internal annular recess 14104 f of the tubular body 14104 a and an engagement member 14108 that includes a base member 14108 a having a tapered end 14108 b and a key member 14108 c having a tapered end 14108 d is received within an opposite portion of the internal annular recess 14104 f of the tubular body 14104 a. Spring members, 14110 and 14112, are received within the annular recess 14104 f of the tubular body 14104 a for biasing the base members, base member 14106 a and 14108 a, of the engagement members, 14106 and 14108, respectively, radially inwardly relative to the tubular body 14104 a.

In an exemplary embodiment, during operation of the casing cutter assembly 14, as illustrated in FIGS. 11Z1 to 11Z4, the one-shot deactivation device 14104 are positioned proximate and in intimate contact with the pins, 14102 a and 14102 b, with the tapered ends, 14106 b and 14108 b, of the base members, 14106 a and 14108 a, of the engagement members, 14106 and 14108, received within the external annular recess 14008 ac of the tubular toggle bushing 14008. When the one-shot deactivation device 14104 is positioned as illustrated in FIG. 11Z, the external annular recess 14104 d of the tubular body 14104 a of the one-shot deactivation device is moved out of engagement with the engagement arms, 14026 d and 14032 d, of the triggers, 14026 and 14032, respectively. As a result, the triggers, 14026 and 14032, may operate normally as described above with reference to FIGS. 11W, 11X, and 11Y.

Conversely, in an exemplary embodiment, during operation of the casing cutter assembly 14, as illustrated in FIGS. 11AA1 to 11AA4, the one-shot deactivation device 14104 are positioned proximate and in intimate contact with the pins, 14100 a and 14100 b, with the tapered ends, 14106 b and 14108 b, of the base members, 14106 a and 14108 a, of the engagement members, 14106 and 14108, not received within the external annular recess 14008 ac of the tubular toggle bushing 14008. When the one-shot deactivation device 14104 is positioned as illustrated in FIGS. 11AA1 to 11AA4, the external annular recess 14104 d of the tubular body 14104 a of the one-shot deactivation device is moved into engagement with the engagement arms, 14026 d and 14032 d, of the triggers, 14026 and 14032, respectively. As a result, the triggers, 14026 and 14032, are deactivated and may not operate normally as described above with reference to FIGS. 11W, 11X, and 11Y.

In an alternative embodiment, the elements of the casing cutter assembly 14 that sense the diameter of the expandable wellbore casing 100 may be disabled or omitted or adjusted to sense any pre-selected internal diameter of the expandable wellbore casing.

In an exemplary embodiment, the ball gripper assembly 16 is provided and operates substantially, at least in part, as disclosed in one or more of the following: (1) PCT patent application serial number PCT/US03/29859, attorney docket no. 25791.102.02, filed on Sep. 22, 2003, (2) PCT patent application serial number PCT/US03/14153, attorney docket number 25791.104.02, filed on Nov. 13, 2003, and/or (3) PCT patent application serial number PCT/US04/007711, attorney docket number 25791.253.02, filed on Mar. 11, 2004, the disclosures of which are incorporated herein by reference.

In an exemplary embodiment, as illustrated in FIGS. 12A1 to 12A4, 12B and 12C1 to 12C4, the ball gripper assembly 16 includes an upper mandrel 1602 that defines a longitudinal passage 1602 a and a radial passage 1602 b and includes an internal threaded connection 1602 c at one end, an external flange 1602 d at an intermediate portion that includes an external annular recess 1602 e having a shoulder 1602 f and an external radial hole 1602 g, an external annular recess 1602 h, an external annular recess 1602 i, an external annular recess 1602 j having a tapered end 1602 k including an external annular recess 1602 ka, an external annular recess 16021, and an external annular recess 1602 m, and an external annular recess 1602 n, an external radial hole 1602 o, an external annular recess 1602 p, and an external annular recess 1602 q at another end.

A sealing member 1614 is received with the external annular recess 1602 i of the external flange 1602 d of the upper mandrel 1602 for sealing the interface between the upper mandrel and the deactivation tubular sleeve 1608. An annular spacer element 1616 is received within the external annular recess 1602 ka of the tapered end 1602 k of the external annular recess 1602 j of the upper mandrel 1602.

One or more inner engagement elements 1618 a of a tubular coglet 1618 engage and are received within the external annular recess 1602 ka of the tapered end 1602 k of the external annular recess 1602 j of the upper mandrel 1602 and one or more outer engagement elements 1618 b of the coglet engage and are received within the internal annular recess 1608 d of the deactivation tubular sleeve 1608.

An external annular recess 1620 a of an end of a tubular coglet prop 1620 that includes an inner flange 1620 b receives and mates with the inner surfaces of the outer engagement elements 1618 b of the coglet 1618.

An end of a tubular bumper sleeve 1624 that includes internal and external flanges, 1624 a and 1624 b, and a hole 1624 c at another end mates with and receives the external annular recess 1602 m of the external flange 1602 d of the upper mandrel 1602. A coglet spring 1626 is received within an annulus 1628 defined between the external annular recess 1602 m of the external flange 1602 d of the upper mandrel 1602, the tubular coglet prop 1620, the inner flange 1620 b of the tubular coglet prop, an end face of the tubular bumper sleeve 1624, and the internal annular recess 1608 c of the deactivation tubular sleeve 1608.

A tubular ball race 1628 that defines a plurality of tapered annular recesses 1628 a and an internally threaded radial opening 1628 b and includes one or more axial engagement elements 1628 c at one end and one or more axial engagement elements 1628 d at another end receives and mates with the other end of the upper mandrel 1602. In an exemplary embodiment, the axial engagement elements 1628 c of the tubular ball race 1628 are received within and are coupled to the hole 1624 c of the tubular bumper sleeve 1624. An end of a tubular activation sleeve 1630 that defines a plurality of radial openings 1630 a, a radial opening 1630 b, a radial opening 1630 c, and includes an internal annular recess 1630 d receives and mates with the tubular ball race 1628. In an exemplary embodiment, an end face of an end of the tubular activation sleeve 1630 is positioned proximate and in opposing relation to an end face of an end of the deactivation sleeve 1608. In an exemplary embodiment, the radial openings 1630 a are aligned with and positioned in opposing relation to corresponding of tapered annular recesses 1628 a of the tubular ball race 1628, and the radial openings are also narrowed in cross section in the radial direction for reasons to be described.

Balls 1632 are received within each of the of tapered annular recesses 1628 a and corresponding radial openings 1630 a of the tubular ball race 1628 and tubular activation sleeve 1630, respectively. In an exemplary embodiment, the narrowed cross sections of the radial openings 1630 a of the tubular activation sleeve 1630 will permit the balls 1632 to be displaced outwardly in the radial direction until at least a portion of the balls extends beyond the outer perimeter of the tubular activation sleeve to thereby permit engagement of the balls with an outer structure such as, for example, a wellbore casing.

A lower mandrel 1634 that defines a longitudinal passage 1634 a and an internally threaded radial passage 1634 b at one end and includes internal annular recesses, 1634 c and 1634 d, for receiving and mating with the external annular recesses, 1602 p and 1602 q, of the upper mandrel 1602, an internal annular recess 1634 e, an external flange 1634 f, and an externally threaded connection 1634 g at another end. In an exemplary embodiment, as illustrated in FIG. 12B, the end of the lower mandrel 1634 further includes longitudinal recesses 1634 h for receiving and mating with corresponding axial engagement elements 1628 d of the tubular ball race 1628. A sealing element 1635 is received within the internal annular recess 1634 d of the lower mandrel 1634 for sealing an interface between the lower mandrel and the external annular recess 1602 p of the upper mandrel 1602.

A tubular spring retainer 1636 that defines a radial passage 1636 a and includes an external annular recess 1636 b at one end mates with and receives the end of the lower mandrel 1634 and is positioned proximate an end face of the external flange 1634 f of the lower mandrel. A tubular spring retainer 1638 receives and mates with the end of the lower mandrel 1634 and is received and mates with the internal annular recess 1630 d of the tubular activation sleeve 1630.

An activation spring 1640 is received within an annulus 1642 defined an end face of the tubular spring retainer 1638, an end face of the spring retainer 1636, the internal annular recess 1630 d of the tubular activation sleeve 1630, and the end of the lower mandrel 1634. A retainer screw 1642 is received within and is threadably coupled to the internally threaded radial opening 1634 b of the lower mandrel 1634 that also extends into the external radial hole 1602 o of the upper mandrel 1602.

During operation of the ball gripper assembly 16, in an exemplary embodiment, as illustrated in FIGS. 12A1 to 12A4, the ball gripper assembly may be positioned within the expandable wellbore casing 100 and the internally threaded connection 1602 c of the upper mandrel 1602 may be coupled to an externally threaded connection 14 a of an end of the casing cutter assembly 14 and the externally threaded connection 1634 g of the lower mandrel 1634 may be coupled to an internally threaded connection 18 a of an end of the tension actuator assembly 18.

In an alternative embodiment, the internally threaded connection 1602 c of the upper mandrel 1602 may be coupled to an externally threaded connection of an end of the tension actuator assembly 18 and the externally threaded connection 1634 g of the lower mandrel 1634 may be coupled to an internally threaded connection of an end of casing cutter assembly 14.

In an exemplary embodiment, the deactivation spring 1610 has a greater spring rate than the activation spring 1640. As a result, in an initial operating mode, as illustrated in FIGS. 12A1 to 12A4, a biasing spring force is applied to the deactivation sleeve 1608 and activation sleeve 1630 in a direction 1644 that maintains the activation sleeve in a position relative to the tubular ball race 1628 that maintains the balls 1632 within the radially inward portions of the corresponding tapered annular recesses 1628 a of the tubular ball race such that the balls do not extend beyond the perimeter of the activation sleeve to engage the expandable wellbore casing 100.

As illustrated in FIGS. 12C1 to 12C4, in an exemplary embodiment, the ball gripper 16 may be operated to engage the interior surface of the expandable wellbore casing 100 by injecting a fluidic material 1650 into the ball gripper assembly through the longitudinal passages 1602 a and 1634 aa, of the upper and lower mandrels, 1602 and 1634, respectively.

In particular, when the longitudinal and radial passages, 1602 a and 1602 b, respectively, of the upper mandrel 1602 are pressurized by the injection of the fluidic material 1650, the internal annular recess 1608 c of the deactivation tubular sleeve 1608 is pressurized. When the operating pressure of the fluidic material 1650 within the internal annular recess 1608 c of the deactivation tubular sleeve 1608 is sufficient to overcome the biasing spring force of the deactivation spring 1610, the deactivation tubular sleeve is displaced in a direction 1652. As a result, the spring force provided by the activation spring 1640 then may displace the activation tubular sleeve 1630 in the direction 1652 thereby moving the balls 1632 on the corresponding tapered annular recesses 1628 a of the tubular ball race 1628 outwardly in a radial direction into engagement with the interior surface of the expandable wellbore casing 100. In an exemplary embodiment, the operating pressure of the fluidic material 1650 sufficient to overcome the biasing spring force of the deactivation spring 1610 was about 100 psi.

In an exemplary embodiment, when the operating pressure of the fluidic material 1650 is reduced, the operating pressure of the fluidic material 1650 within the internal annular recess 1608 c of the deactivation tubular sleeve 1608 is no longer sufficient to overcome the biasing spring force of the deactivation spring 1610, and the deactivation tubular sleeve and the activation tubular sleeve 1630 are displaced in a direction opposite to the direction 1652 thereby moving the balls 1632 radially inwardly and out of engagement with the interior surface of the expandable wellbore casing 100.

In an exemplary embodiment, the ball gripper assembly 16 is operated to engage the interior surface of the expandable wellbore casing 100 in combination with the operation of the tension actuator assembly 18 to apply an upward tensile force to one or more elements of the system 10 coupled to and positioned below the tension actuator assembly. As a result, a reaction force comprising a downward tensile force is applied to the lower mandrel 1634 of the ball gripper assembly 16 in a direction opposite to the direction 1652 during the operation of the tension actuator assembly 18. Consequently, due to the geometry of the tapered 1628 a of the tubular ball race 1628, the balls 1632 are driven up the tapered annular recesses 1628 a of the tubular ball race 1628 with increased force and the contact force between the balls 1632 and the interior surface of the expandable wellbore casing 100 is significantly increased thereby correspondingly increasing the gripping force and effect of the ball gripper assembly.

In an exemplary embodiment, the ball gripper assembly 16 may be operated to radially expand and plastically deform discrete portions of the expandable wellbore casing 100 by controlling the amount of contact force applied to the interior surface of the expandable wellbore casing by the balls 1632 of the ball gripper assembly.

In an exemplary embodiment, as illustrated in FIGS. 13A1 to 13A8, during operation of the tension actuator assembly 18, the tension actuator assembly is positioned within the expandable wellbore casing 100 and fluidic material 13200 is injected into the tension actuator assembly through the passages 18002 a, 18016 a, 18066 a, 18070 a, 18076 a, 18080 a, 18086 a, 18090 a, 18096 a, 18100 a, 18106 a, 18110 a, and 18116 a.

In an exemplary embodiment, during the upward displacement of the tubular pistons, 18070, 18080, 18090, 18100, and 18110, fluidic materials displaced by the tubular pistons within discharge annular chambers, 13214, 13216, 13218, 13220, and 13222 are exhausted out of the tension actuator assembly 18 through the radial passages, 18008 d and 18008 e, 18022 d and 18022 e, 18030 d and 18030 e, 18040 d and 18040 e, 18050 d and 18050 e, respectively. Furthermore, in an exemplary embodiment, the upward displacement of the tubular pistons, 18070, 18080, 18090, 18100, and 18110, further causes the external splines 18066 d of the connector tube 18066 to engage the internal splines 18014 b of the tubular member 18014 and the circumferentially spaced apart teeth 18116 g of the connector tube 18116 to engage the circumferentially spaced teeth 18060 f of the tubular lower stop 18060. As a result of the interaction of the external splines 18066 d of the connector tube 18066 to engage the internal splines 18014 b of the tubular member 18014 and the circumferentially spaced apart teeth 18116 g of the connector tube 18116 to engage the circumferentially spaced teeth 18060 f of the tubular lower stop 18060, torsional loads may be transmitted through the tension actuator assembly 18.

An end face of the release piston 28084 is positioned in opposing relation to an end face of the locking dogs 28080.

A release sleeve 28088 that receives and is mounted upon the locking dogs 28080 and the release piston 28084 includes an internal flange 28088 a at one end that sealingly engages the tubular lower mandrel 28006. A bypass sleeve 28090 that receives and is mounted upon the release sleeve 28088 includes an internal flange 28090 a at one end.

In an exemplary embodiment, during operation of the adjustable bell section expansion cone assembly 28, the retracting spring 28044 is compressed and thereby applies a biasing spring force in a direction 28092 from the lower tubular mandrel 28006 to the tubular spring housing 28034 that, in the absence of other forces, moves and/or maintains the upper cam assembly 28052 and the upper expansion segments 28054 out of engagement with the lower expansion segments 28058 and the lower cam assembly 28060. In an exemplary embodiment, during operation of the adjustable bell section expansion cone assembly 28, an external threaded connection 20 a of an end of the sealing cup assembly 20 is coupled to the internal threaded connection 28002 d of the upper tubular tool joint 28002 and an internal threaded connection 30 a of an end of the adjustable casing expansion cone assembly 30 is coupled to the external threaded connection 28068 f of the tubular member 28068.

The upper cam assembly 28052 and the upper expansion segments 28054 may be brought into engagement with the lower expansion segments 28058 and the lower cam assembly 28060 by pressurizing an annulus 28094 defined between the lower tubular mandrel 28006 and the tubular spring housing 28034. In particular, injection of fluidic materials into the adjustable bell section expansion cone assembly 28 through the longitudinal passage 28006 b of the lower tubular mandrel 28006 and into the radial passage 28006 ba may pressurize the annulus 28094 thereby creating sufficient operating pressure to generate a force in a direction 28096 sufficient to overcome the biasing force of the retracting spring 28044. As a result, the spring housing 28034 may be displaced in the direction 28096 relative to the lower tubular mandrel 28006 thereby displacing the tubular upper hinge sleeve 28050, upper cam assembly 28052, and upper expansion segments 28054 in the direction 28096.

In an exemplary embodiment, as illustrated in FIGS. 15P and 15R, the displacement of the upper cam assembly 28052 and upper expansion segments 28054 in the direction 28096 will cause the lower expansion segments 28058 to ride up the cam surfaces 28052 e of the cam arms 28052 d of the upper cam assembly 28052 while also pivoting about the lower tubular hinge segment 28064, and will also cause the upper expansion segments 28054 to ride up the cam surfaces 28060 e of the cam arms 28060 d of the lower cam assembly 28060 while also pivoting about the upper tubular hinge segment 28050. In an exemplary embodiment, when the upper and lower expansion segments, 28054 and 28058, are brought into axial alignment, they define an outer expansion surface that is approximately contiguous in a circumferential direction and which provides an outer expansion surface that at least approximates a conical surface.

In an exemplary embodiment, during the operation of the adjustable bell section expansion cone assembly 28, when the upper and lower expansion segments, 28054 and 28058, brought into axial alignment into a radially expanded position, the upper and lower expansion segments, 28054 and 28058, are displaced relative to the expandable wellbore casing 100 to thereby radially expand and plastically deform at least a portion of the expandable wellbore casing. In an exemplary embodiment, during the radial expansion and plastic deformation of the expandable wellbore casing 100, the adjustable bell section expansion cone assembly 28 may then be rotated relative to the expandable wellbore casing to enhance and/or modify the rate at which the expandable wellbore casing is radially expanded and plastically deformed.

In an exemplary embodiment, the upper cam assembly 28052 and the upper expansion segments 28054 may be moved out of engagement with the lower expansion segments 28058 and the lower cam assembly 28060 by reducing the operating pressure within the annulus 28094.

In an alternative embodiment, as illustrated in FIGS. 15S, 15T, 15U and 15V, during operation of the adjustable bell section expansion cone assembly 28, the upper cam assembly 28052 and the upper expansion segments 28054 may also be moved out of engagement with the lower expansion segments 28058 and the lower cam assembly 28060 by sensing the operating pressure within the longitudinal passage 28006 b of the lower tubular mandrel 28006. In particular, as illustrated in FIG. 15T, if the operating pressure within the longitudinal passage 28006 b and radial passage 28006 bb of the lower tubular mandrel 28006 exceeds a predetermined value, the burst disc 28086 will open the passage 28084 a thereby pressurizing the interior of the tubular release sleeve 28088 thereby displacing the tubular release sleeve 28088 downwardly in a direction 28092 away from engagement with the locking dogs 28080.

As a result, as illustrated in FIG. 15U, the locking dogs 28080 are displaced outwardly in the radial directed and thereby released from engagement with the lower tubular mandrel 28006 thereby permitting the lower expansion segments 28058 and the lower cam assembly 28060 to be displaced downwardly relative to the lower tubular mandrel.

As a result, as illustrated in FIG. 15V, the operating pressure within the lower tubular mandrel 28066 may then cause the lower tubular mandrel to be displaced downwardly in the direction 28094 relative to the tubular lower mandrel 28006 and the retracting piston 28074. As a result, the lower tubular mandrel 28066, the lower expansion segments 28058, the lower cam assembly 28060, and tubular lower hinge sleeve 28064 are displaced downwardly in the direction 28094 relative to the tubular spring housing 28034 thereby moving the lower expansion segments 28058 and the lower cam assembly 28060 out of engagement with the upper cam assembly 28052 and the upper expansion segments 28054.

In an exemplary embodiment, as illustrated in FIGS. 15W, 15X, and 15Y, during operation of the adjustable bell section expansion cone assembly 28, the adjustable bell section expansion cone assembly senses the diameter of the expandable wellbore casing 100 using the upper toggle links, 28022 and 28028, lower toggle links, 28024 and 28030, and triggers, 28026 and 28032, and then prevents the engagement of the upper cam assembly 28052 and the upper expansion segments 28054 with the lower expansion segments 28058 and the lower cam assembly 28060.

In particular, as illustrated in FIG. 15W, anytime the upper toggle links, 28022 and 28028, and lower toggle links, 28024 and 28030, are positioned within a portion of the expandable wellbore casing 100 that has been radially expanded and plastically deformed by the system 10, the triggers, 28026 and 28032, will be pivoted by the engagement arms, 28024 d and 28030 d, of the lower toggle links, 28024 and 28030, to a position in which the triggers will no longer engage the internal flange 28034 d of the end of the tubular spring housing 28034 thereby permitting the displacement of the tubular spring housing in the direction 28096. As a result, the upper cam assembly 28052 and the upper expansion segments 28054 can be brought into engagement with the lower expansion segments 28058 and the lower cam assembly 28060. In an exemplary embodiment, the upper toggle links, 28022 and 28028, and the lower toggle links, 28024 and 28030, are spring biased towards the position illustrated in FIG. 15W.

Conversely, as illustrated in FIG. 15X, anytime the upper toggle links, 28022 and 28028, and lower toggle links, 28024 and 28030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10, the triggers, 28026 and 28032, will be maintained in a position in which the triggers will engage the internal flange 28034 d of the end of the tubular spring housing 28034 thereby preventing the displacement of the tubular spring housing in the direction 28096. As a result, the upper cam assembly 28052 and the upper expansion segments 28054 cannot be brought into engagement with the lower expansion segments 28058 and the lower cam assembly 28060. In an exemplary embodiment, the triggers, 28026 and 28032, are spring biased towards the position illustrated in FIG. 15X.

In an exemplary embodiment, as illustrated in FIG. 15Y, the tubular spring housing 28034 may be displaced upwardly in the direction 28098 even if the upper toggle links, 28022 and 28028, and lower toggle links, 28024 and 28030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10.

In an exemplary embodiment, as illustrated in FIGS. 15Z1 to 15Z4, 15AA1 to 15AA4, 15AB1 to 15AB4, 15AC1 to 15AC4, 15AD, and 15AE, the tubular spring housing 28034 of the adjustable bell section expansion cone assembly 28 defines internal annular recesses 28034 k and 28034 l, spaced apart by an internal flange 28034 m, the tubular toggle bushing 28008 defines an external annular recess 28008 ac, and the adjustable bell section expansion cone assembly further includes pins, 28100 a and 28100 b and 28102 a and 28102 b, mounted in holes 28008 j and 28008 o and 28008 k and 28008 n, respectively, of the tubular toggle bushing, and a one-shot deactivation device 28104 mounted on the tubular toggle bushing between the pins, 28100 a and 28100 b and 28102 a and 28102 b.

The one-shot deactivation device 28104 includes a tubular body 28104 a that defines radial holes, 28104 b and 28014 c, and includes an external annular recess 28104 d at one end, a centrally positioned external flange 28104 e, a centrally positioned internal annular recess 28104 f, and an external annular recess 28104 g at another end. An engagement member 28106 that includes a base member 28106 a having a tapered end 28106 b and a key member 28106 c having a tapered end 28106 d is received within a portion of the internal annular recess 28104 f of the tubular body 28104 a and an engagement member 28108 that includes a base member 28108 a having a tapered end 28108 b and a key member 28108 c having a tapered end 28108 d is received within an opposite portion of the internal annular recess 28104 f of the tubular body 28104 a. Spring members, 28110 and 28112, are received within the annular recess 28104 f of the tubular body 28104 a for biasing the base members, base member 28106 a and 28108 a, of the engagement members, 28106 and 28108, respectively, radially inwardly relative to the tubular body 28104 a.

In an exemplary embodiment, during operation of the adjustable bell section expansion cone assembly 28, as illustrated in FIGS. 15Z1 to 15Z4, the one-shot deactivation device 28104 are positioned proximate and in intimate contact with the pins, 28102 a and 28102 b, with the tapered ends, 28106 b and 28108 b, of the base members, 28106 a and 28108 a, of the engagement members, 28106 and 28108, received within the external annular recess 28008 ac of the tubular toggle bushing 28008. When the one-shot deactivation device 28104 is positioned as illustrated in FIGS. 15Z1 to 15Z4, the external annular recess 28104 d of the tubular body 28104 a of the one-shot deactivation device is moved out of engagement with the engagement arms, 28026 d and 28032 d, of the triggers, 28026 and 28032, respectively. As a result, the triggers, 28026 and 28032, may operate normally as described above with reference to FIGS. 15W, 15X, and 15Y.

Conversely, in an exemplary embodiment, during operation of the adjustable bell section expansion cone assembly 28, as illustrated in FIGS. 15AA1 to 15AA4, the one-shot deactivation device 28104 are positioned proximate and in intimate contact with the pins, 28100 a and 28100 b, with the tapered ends, 28106 b and 28108 b, of the base members, 28106 a and 28108 a, of the engagement members, 28106 and 28108, not received within the external annular recess 28008 ac of the tubular toggle bushing 28008. When the one-shot deactivation device 28104 is positioned as illustrated in FIG. 15AA, the external annular recess 28104 d of the tubular body 28104 a of the one-shot deactivation device is moved into engagement with the engagement arms, 28026 d and 28032 d, of the triggers, 28026 and 28032, respectively. As a result, the triggers, 28026 and 28032, are deactivated and may not operate normally as described above with reference to FIGS. 15W, 15X, and 15Y.

In an alternative embodiment, the elements of the adjustable bell section expansion cone assembly 28 that sense the diameter of the expandable wellbore casing 100 may be disabled or omitted or adjusted to sense any pre-selected internal diameter of the expandable wellbore casing.

In an exemplary embodiment, during operation of the adjustable casing expansion cone assembly 30, the retracting spring 30044 is compressed and thereby applies a biasing spring force in a direction 30092 from the lower tubular mandrel 30006 to the tubular spring housing 30034 that, in the absence of other forces, moves and/or maintains the upper cam assembly 30052 and the upper expansion segments 30054 out of engagement with the lower expansion segments 30058 and the lower cam assembly 30060. In an exemplary embodiment, during operation of the adjustable bell section expansion cone assembly 28, an external threaded connection 20 a of an end of the sealing cup assembly 20 is coupled to the internal threaded connection 30002 d of the upper tubular tool joint 30002 and an internal threaded connection 30 a of an end of the adjustable casing expansion cone assembly 30 is coupled to the external threaded connection 30068 f of the tubular member 30068.

The upper cam assembly 30052 and the upper expansion segments 30054 may be brought into engagement with the lower expansion segments 30058 and the lower cam assembly 30060 by pressurizing an annulus 30094 defined between the lower tubular mandrel 30006 and the tubular spring housing 30034. In particular, injection of fluidic materials into the adjustable casing expansion cone assembly 30 through the longitudinal passage 30006 b of the lower tubular mandrel 30006 and into the radial passage 30006 ba may pressurize the annulus 30094 thereby creating sufficient operating pressure to generate a force in a direction 30096 sufficient to overcome the biasing force of the retracting spring 30044. As a result, the spring housing 30034 may be displaced in the direction 30096 relative to the lower tubular mandrel 30006 thereby displacing the tubular upper hinge sleeve 30050, upper cam assembly 30052, and upper expansion segments 30054 in the direction 30096.

In an exemplary embodiment, as illustrated in FIGS. 16P, 16Q, and 16R, the displacement of the upper cam assembly 30052 and upper expansion segments 30054 in the direction 30096 will cause the lower expansion segments 30058 to ride up the cam surfaces 30052 e of the cam arms 30052 d of the upper cam assembly 30052 while also pivoting about the lower tubular hinge segment 30064, and will also cause the upper expansion segments 30054 to ride up the cam surfaces 30060 e of the cam arms 30060 d of the lower cam assembly 30060 while also pivoting about the upper tubular hinge segment 30050. In an exemplary embodiment, when the upper and lower expansion segments, 30054 and 30058, are brought into axial alignment, they define an outer expansion surface that is approximately contiguous in a circumferential direction and which provides an outer expansion surface that at least approximates a conical surface.

In an exemplary embodiment, during the operation of the adjustable casing expansion cone assembly 30, when the upper and lower expansion segments, 30054 and 30058, brought into axial alignment into a radially expanded position, the upper and lower expansion segments, 30054 and 30058, are displaced relative to the expandable wellbore casing 100 to thereby radially expand and plastically deform at least a portion of the expandable wellbore casing. In an exemplary embodiment, during the radial expansion and plastic deformation of the expandable wellbore casing 100, the adjustable casing expansion cone assembly 30 may then be rotated relative to the expandable wellbore casing to enhance and/or modify the rate at which the expandable wellbore casing is radially expanded and plastically deformed.

In an exemplary embodiment, the upper cam assembly 30052 and the upper expansion segments 30054 may be moved out of engagement with the lower expansion segments 30058 and the lower cam assembly 30060 by reducing the operating pressure within the annulus 30094.

In an alternative embodiment, as illustrated in FIGS. 16S, 16T, 16U and 16V, during operation of the adjustable casing expansion cone assembly 30, the upper cam assembly 30052 and the upper expansion segments 30054 may also be moved out of engagement with the lower expansion segments 30058 and the lower cam assembly 30060 by sensing the operating pressure within the longitudinal passage 30006 b of the lower tubular mandrel 30006. In particular, as illustrated in FIG. 16T, if the operating pressure within the longitudinal passage 30006 b and radial passage 30006 bb of the lower tubular mandrel 30006 exceeds a predetermined value, the burst disc 30086 will open the passage 30084 a thereby pressurizing the interior of the tubular release sleeve 30088 thereby displacing the tubular release sleeve 30088 downwardly in a direction 30092 away from engagement with the locking dogs 30080.

As a result, as illustrated in FIG. 16U, the locking dogs 30080 are displaced outwardly in the radial directed and thereby released from engagement with the lower tubular mandrel 30006 thereby permitting the lower expansion segments 30058 and the lower cam assembly 30060 to be displaced downwardly relative to the lower tubular mandrel.

As a result, as illustrated in FIG. 16V, the operating pressure within the lower tubular mandrel 30066 may then cause the lower tubular mandrel to be displaced downwardly in the direction 30094 relative to the tubular lower mandrel 30006 and the retracting piston 30074. As a result, the lower tubular mandrel 30066, the lower expansion segments 30058, the lower cam assembly 30060, and tubular lower hinge sleeve 30064 are displaced downwardly in the direction 30094 relative to the tubular spring housing 30034 thereby moving the lower expansion segments 30058 and the lower cam assembly 30060 out of engagement with the upper cam assembly 30052 and the upper expansion segments 30054.

In an exemplary embodiment, as illustrated in FIGS. 16W, 16X, and 16Y, during operation of the adjustable casing expansion cone assembly 30, the adjustable casing expansion cone assembly senses the diameter of the expandable wellbore casing 100 using the upper toggle links, 30022 and 30028, lower toggle links, 30024 and 30030, and triggers, 30026 and 30032, and then prevents the engagement of the upper cam assembly 30052 and the upper expansion segments 30054 with the lower expansion segments 30058 and the lower cam assembly 30060.

In particular, as illustrated in FIG. 16W, anytime the upper toggle links, 30022 and 30028, and lower toggle links, 30024 and 30030, are positioned within a portion of the expandable wellbore casing 100 that has been radially expanded and plastically deformed by the system 10, the triggers, 30026 and 30032, will be pivoted by the engagement arms, 30024 d and 30030 d, of the lower toggle links, 30024 and 30030, to a position in which the triggers will no longer engage the internal flange 30034 d of the end of the tubular spring housing 30034 thereby permitting the displacement of the tubular spring housing in the direction 30096. As a result, the upper cam assembly 30052 and the upper expansion segments 30054 can be brought into engagement with the lower expansion segments 30058 and the lower cam assembly 30060. In an exemplary embodiment, the upper toggle links, 30022 and 30028, and the lower toggle links, 30024 and 30030, are spring biased towards the position illustrated in FIG. 16W.

Conversely, as illustrated in FIG. 16X, anytime the upper toggle links, 30022 and 30028, and lower toggle links, 30024 and 30030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10, the triggers, 30026 and 30032, will be maintained in a position in which the triggers will engage the internal flange 30034 d of the end of the tubular spring housing 30034 thereby preventing the displacement of the tubular spring housing in the direction 30096. As a result, the upper cam assembly 30052 and the upper expansion segments 30054 cannot be brought into engagement with the lower expansion segments 30058 and the lower cam assembly 30060. In an exemplary embodiment, the triggers, 30026 and 30032, are spring biased towards the position illustrated in FIG. 16X.

In an exemplary embodiment, as illustrated in FIG. 16Y, the tubular spring housing 30034 may be displaced upwardly in the direction 30098 even if the upper toggle links, 30022 and 30028, and lower toggle links, 30024 and 30030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10.

In an exemplary embodiment, as illustrated in FIGS. 16Z1 to 16Z4, 16AA1 to 16AA4, 16AB1 to 16AB4, 16AC1 to 16AC4, 16AD, and 16AE, the tubular spring housing 30034 of the adjustable casing expansion cone assembly 30 defines internal annular recesses 30034 k and 30034 l, spaced apart by an internal flange 30034 m, the tubular toggle bushing 30008 defines an external annular recess 30008 ac, and the adjustable casing expansion cone assembly further includes pins, 30100 a and 30100 b and 30102 a and 30102 b, mounted in holes 30008 j and 30008 o and 30008 k and 30008 n, respectively, of the tubular toggle bushing, and a one-shot deactivation device 30104 mounted on the tubular toggle bushing between the pins, 30100 a and 30100 b and 30102 a and 30102 b.

The one-shot deactivation device 30104 includes a tubular body 30104 a that defines radial holes, 30104 b and 30014 c, and includes an external annular recess 30104 d at one end, a centrally positioned external flange 30104 e, a centrally positioned internal annular recess 30104 f, and an external annular recess 30104 g at another end. An engagement member 30106 that includes a base member 30106 a having a tapered end 30106 b and a key member 30106 c having a tapered end 30106 d is received within a portion of the internal annular recess 30104 f of the tubular body 30104 a and an engagement member 30108 that includes a base member 30108 a having a tapered end 30108 b and a key member 30108 c having a tapered end 30108 d is received within an opposite portion of the internal annular recess 30104 f of the tubular body 30104 a. Spring members, 30110 and 30112, are received within the annular recess 30104 f of the tubular body 30104 a for biasing the base members, base member 30106 a and 30108 a, of the engagement members, 30106 and 30108, respectively, radially inwardly relative to the tubular body 30104 a.

In an exemplary embodiment, during operation of the adjustable bell section expansion cone assembly 28, as illustrated in FIG. 16Z, the one-shot deactivation device 30104 are positioned proximate and in intimate contact with the pins, 30102 a and 30102 b, with the tapered ends, 30106 b and 30108 b, of the base members, 30106 a and 30108 a, of the engagement members, 30106 and 30108, received within the external annular recess 30008 ac of the tubular toggle bushing 30008. When the one-shot deactivation device 30104 is positioned as illustrated in FIG. 16Z, the external annular recess 30104 d of the tubular body 30104 a of the one-shot deactivation device is moved out of engagement with the engagement arms, 30026 d and 30032 d, of the triggers, 30026 and 30032, respectively. As a result, the triggers, 30026 and 30032, may operate normally as described above with reference to FIGS. 16W, 16X, and 16Y.

Conversely, in an exemplary embodiment, during operation of the adjustable casing expansion cone assembly 30, as illustrated in FIGS. 16AA1 to 16AA4, the one-shot deactivation device 30104 are positioned proximate and in intimate contact with the pins, 30100 a and 30100 b, with the tapered ends, 30106 b and 30108 b, of the base members, 30106 a and 30108 a, of the engagement members, 30106 and 30108, not received within the external annular recess 30008 ac of the tubular toggle bushing 30008. When the one-shot deactivation device 30104 is positioned as illustrated in FIGS. 16AA1 to 16AA4, the external annular recess 30104 d of the tubular body 30104 a of the one-shot deactivation device is moved into engagement with the engagement arms, 30026 d and 30032 d, of the triggers, 30026 and 30032, respectively. As a result, the triggers, 30026 and 30032, are deactivated and may not operate normally as described above with reference to FIGS. 16W, 16X, and 16Y.

In an alternative embodiment, the elements of the adjustable casing expansion cone assembly 30 that sense the diameter of the expandable wellbore casing 100 may be disabled or omitted or adjusted to sense any pre-selected internal diameter of the expandable wellbore casing.

In an exemplary embodiment, as illustrated in FIGS. 19A1 to 19A5, during the operation of the packer setting tool assembly 32 and packer assembly 36, the packer setting tool and packer assembly are coupled to one another by inserting the end of the tubular upper adaptor 3602 into the other end of the tubular coupling ring 3244, bringing the circumferentially spaced teeth 3216 g of the other end of the tubular bushing 3216 into engagement with the circumferentially spaced teeth 3602 e of the end of the tubular upper adaptor, and mounting shear pins, 36100 a and 36100 b, within the mounting holes, 3244 c and 3602 c, and, 3244 d and 3602 d, respectively, of the tubular coupling ring and tubular upper adaptor, respectively. As a result, the tubular mandrel 3206 and tubular stinger 3208 of the packer setting tool assembly 32 are thereby positioned within the longitudinal passage 3604 a of the tubular upper mandrel 3604 with the 3208 e of the tubular stinger positioned within the longitudinal passage 3646 b of the tubular lower mandrel 3646 proximate the collet fingers 3650 d of the tubular sliding sleeve valve 3650.

Furthermore, in an exemplary embodiment, during the operation of the packer setting tool 32 and packer assembly 36, as illustrated in FIGS. 19A1 to 19A5, the packer setting tool and packer assembly are positioned within the expandable wellbore casing 100 and an internal threaded connection 30 a of an end of the adjustable casing expansion cone assembly 30 receives and is coupled to the external threaded connection 3202 f of the end of the tubular adaptor 3202 of the packer setting tool assembly. Furthermore, shear pins, 36102 a and 36102 b, mounted within the mounting holes, 3658 b and 3658 c, of the tubular outer sleeve 3658 couple the tubular outer sleeve to the expandable wellbore casing. As a result, torsion loads may transferred between the tubular outer sleeve 3658 and the expandable wellbore casing 100.

In an exemplary embodiment, as illustrated in FIGS. 19B1 to 19B5, a conventional plug 36104 is then injected into the setting tool assembly 32 and packer assembly 36 by injecting a fluidic material 36106 into the setting tool assembly and packer assembly through the longitudinal passages, 3202 a, 3204 b, 3206 b, 3208 b, 3650 a, 3646 a, 3660 b, and 3664 a of the tubular adaptor 3202, tubular upper mandrel 3204, tubular mandrel 3206, tubular stinger 3208, tubular sliding sleeve valve 3650, tubular lower mandrel 3646, tubular bypass mandrel 3660, and tubular plug seat 3664, respectively. The plug 36104 is thereby positioned within the longitudinal passage 3664 a of the tubular plug seat 3664. Continued injection of the fluidic material 36106 following the seating of the plug 1606 within the longitudinal passage 3664 a of the tubular plug seat 3664 causes the plug and the tubular plug seat to be displaced downwardly in a direction 36108 until further movement of the tubular plug seat is prevented by interaction of the set screw 3674 with the external annular recess 3664 f of the tubular plug seat. As a result, the flow ports, 3664 c and 3664 d, of the tubular plug seat 3664 are moved out of alignment with the upper flow ports, 3660 c and 3660 d, of the tubular bypass mandrel 3660.

In an exemplary embodiment, as illustrated in FIGS. 19C1 to 19C5, after the expandable wellbore casing 100 has been radially expanded and plastically deformed to form at least the bell section 112 of the expandable wellbore casing 100 thereby shearing the shear pins, 36102 a and 36102 b, the setting tool assembly 32 and packer assembly 36 are then moved upwardly to a position within the expandable wellbore casing 100 above the bell section. The tubular adaptor 3202 is then rotated, by rotating the tool string of the system 10 above the setting tool assembly 32, to displace and position the drag blocks, 3228 and 3230, into engagement with the interior surface of the expandable wellbore casing 100.

As a result of the engagement of the drag blocks, 3228 and 3230, with the interior surface of the expandable wellbore casing 100, further rotation of the drag blocks relative to the wellbore casing is prevented. Consequently, due to the operation and interaction of the threaded connections, 3216 d and 3218 a, of the tubular bushing 3216 and tubular drag block body 3218, respectively, further rotation of the tubular adaptor 3202 causes the tubular drag block body and setting sleeve 3242 to be displaced downwardly in a direction 36112 relative to the remaining elements of the setting tool assembly 32 and packer assembly 36. As a result, the setting sleeve 3242 engages and displaces the upper tubular spacer ring 3606 thereby shearing the shear pins, 3622 a and 3622 b, and driving the upper tubular slip 3612 onto and up the angled end face 3620 d of the upper tubular wedge 3620 and into engagement with the interior surface of the expandable wellbore casing 100. As a result, longitudinal displacement of the upper tubular slip 3612 relative to the expandable wellbore casing 100 is prevented. Furthermore, as a result, the 3246 b collet fingers of the tubular retaining collet 3246 are disengaged from the tubular upper adaptor 3602.

In an alternative embodiment, after the drag blocks, 3228 and 3230, engage the interior surface of the expandable wellbore casing 100, an upward tensile force is applied to the tubular support member 12, and the ball gripper assembly 16 is then operate to engage the interior surface of the expandable wellbore casing. The tension actuator assembly 18 is then operated to apply an upward tensile force to the tubular adaptor 3202 thereby pulling the upper tubular spacer ring 3606, lower tubular spacer ring 3610, upper tubular slip 3612, lower tubular slip 3616, upper tubular wedge 3620, lower tubular wedge 3624, upper tubular extrusion limiter 3628, lower tubular extrusion limiter 3634, and central tubular elastomeric element 3644 upwardly into contact with the 3242 thereby compressing the upper tubular spacer ring, lower tubular spacer ring, upper tubular slip, lower tubular slip, upper tubular wedge, lower tubular wedge, upper tubular extrusion limiter, lower tubular extrusion limiter, and central tubular elastomeric element. As a result, the upper tubular slip 3612, lower tubular slip 3616, and central tubular elastomeric element 3644 engage the interior surface of the expandable wellbore casing 100.

In an exemplary embodiment, as illustrated in FIGS. 19D1 to 19D5, an upward tensile force is then applied to the tubular adaptor 3202 thereby compressing the lower tubular slip 3616, lower tubular wedge 3624, central elastomeric packer element 3644, upper tubular extrusion limiter 3628, and upper tubular wedge 3620 between the lower tubular spacer ring 3610 and the stationary upper tubular slip 3612. As a result, the lower tubular slip 3616 is driven onto and up the angled end face 3624 d of the lower tubular wedge 3624 and into engagement with the interior surface of the expandable wellbore casing 100, and the central elastomeric packer element 3644 is compressed radially outwardly into engagement with the interior surface of the expandable tubular member. As a result, further longitudinal displacement of the upper tubular slip 3612, lower tubular slip 3616, and central elastomeric packer element 3644 relative to the expandable wellbore casing 100 is prevented.

In an exemplary embodiment, as illustrated in FIGS. 19E1 to 19E6, continued application of the upward tensile force to tubular adaptor 3202 will then shear the shear pins, 1602 a and 1602 b, thereby disengaging the setting tool assembly 32 from the packer assembly 36.

In an exemplary embodiment, as illustrated in FIGS. 19F1 to 19F6, with the drag blocks, 3228 and 3230, in engagement with the interior surface of the expandable wellbore casing 100, the tubular adaptor 102 is further rotated thereby causing the tubular drag block body 3218 and setting sleeve 3242 to be displaced further downwardly in the direction 1612 until the tubular drag block body and setting sleeve are disengaged from the tubular stinger 3208. As a result, the tubular stinger 3208 of the setting tool assembly 32 may then be displaced downwardly into complete engagement with the tubular sliding sleeve valve 3650.

In an exemplary embodiment, as illustrated in FIGS. 19G1 to 19G6, a fluidic material 36114 is then injected into the setting tool assembly 32 and the packer assembly 36 through the longitudinal passages 3202 a, 3204 b, 3206 b, 3208 b, 3604 b, 3650 a, and 3646 b of the tubular adaptor 3202, tubular upper mandrel 3204, tubular mandrel 3206, tubular stinger 3208, tubular upper mandrel 3604, tubular sliding sleeve valve 3650, and tubular lower mandrel 3646, respectively. Because, the plug 36104 is seated within and blocks the longitudinal passage 3664 a of the tubular plug seat 3664, the longitudinal passages 3604 b, 3650 a, and 3646 b of the tubular upper mandrel 3604, tubular sliding sleeve valve 3650, and tubular lower mandrel 3646 are pressurized thereby displacing the tubular upper adaptor 3602 and tubular upper mandrel 3604 downwardly until the end face of the tubular upper mandrel impacts the end face of the upper tubular spacer ring 3606.

In an exemplary embodiment, as illustrated in FIGS. 19H1 to 19H5, the setting tool assembly 32 is brought back into engagement with the packer assembly 36 until the engagement shoulder 3208 e of the other end of the tubular stinger 3208 engages the collet fingers 3650 d of the end of the tubular sliding sleeve valve 3650. As a result, further downward displacement of the tubular stinger 3208 displaces the tubular sliding sleeve valve 3650 downwardly until the radial flow ports, 3650 b and 3650 c, of the tubular sliding sleeve valve are aligned with the flow ports, 3646 e and 3646 f, of the tubular lower mandrel 3646. A hardenable fluidic sealing material 36116 may then be injected into the setting tool assembly 32 and the packer assembly 36 through the longitudinal passages 3202 a, 3204 b, 3206 b, 3208 b, and 3650 a of the tubular adaptor 3202, tubular upper mandrel 3204, tubular mandrel 3206, tubular stinger 3208, and tubular sliding sleeve valve 3650, respectively. The hardenable fluidic sealing material may then flow out of the packer assembly 36 through the upper flow ports, 3658 d and 3658 e, into the annulus between the expandable wellbore casing 100 and the wellbore 102.

The tubular sliding sleeve valve 3650 may then be returned to its original position, with the radial flow ports, 3650 b and 3650 c, of the tubular sliding sleeve valve out of alignment with the flow ports, 3646 e and 3646 f, of the tubular lower mandrel 3646. The hardenable fluidic sealing material 36116 may then be allowed to cure before, during, or after the continued operation of the system 10 to further radially expand and plastically deform the expandable wellbore casing.

In an exemplary embodiment, the system 10 is provided as illustrated in Appendix A to the present application.
